Anti-sleep warning helmet and power limiting system

The present invention relates to preventing sleepiness and staying awake, and more particularly to a sleep prevention warning helmet and an engine power restriction system.

Driving on the road is easy because some factors cause the user to doze off while driving. These factors may be caused by long-term work fatigue, distraction and other factors, so that the vehicle is in the driving lane, which is likely to cause accidents. At present, similar driving safety technology has a method of using ultrasonic to measure the distance between two vehicles as a warning. However, in the two cars at high speed, the reaction time of the fixed pitch is relatively short, so that the safety is relatively low at high speed. In addition, most of the vehicle warnings use visual warnings, which are visual factors to judge the speed of the vehicle and the surrounding environment, but it is impossible to cope with unexpected situations or accidents.

However, sometimes driving may cause the user to be fatigued while driving, or the user may not be able to sleep well due to certain factors. If the user has a doze during driving, the user, the occupant, other passers-by or the vehicle will be in a very dangerous environment, which is extremely likely to cause a car accident or death or injury.

There was a device in the workshop to prevent users from having to drive while driving. The dozing situation occurs. The device is made into a doze warning device by using a mercury balancer. When the user wears the sleep warning device made of the mercury balancer on the head, in case the user drives in the car. When the phenomenon of drowsiness occurs, the mercury balancer in the doze warning device will be tilted due to the user's dozing and head tilting. At this time, the buzzer in the doze warning device will sound to wake up. user. However, this kind of device has poor accuracy, because it is possible that the user does not doze off, but only the head is slightly tilted, and the doze warning device will cause the buzzer to make a false alarm due to the tilt of the mercury balancer, which is extremely undesirable.

In view of the shortcomings derived from the above-mentioned conventional anti-sleep warning helmet and power restriction system, the inventor of the present invention finally successfully developed and completed the anti-sleep warning helmet and power restriction system.

The object of the present invention is to provide an offset angular velocity that exceeds the maximum safety of driving, or to swing the vehicle to the left and right to exceed the safe angular velocity, and to issue a warning sound to alert the user to prevent the user from falling asleep or distracting. Alert the helmet and power limit system.

A second object of the present invention is to provide a sleep-proof warning helmet and power restriction system that detects an offset position of a user's head to generate a tilt condition to reduce the vehicle speed.
